Attorney General Jack Conway was on the backside at Churchill Downs Wednesday morning.

"There is nothing in the general statutes that say that you can't charge what you want for gasoline. If we're not in an emergency situation, the price fluctuates according to the market. So we have fined retailers for gouging. What's happening right now is because we have one supplier and that supplier brings most of the gasoline from the Upper Midwest where they've had floods -- where they have had floods in a disruption in supply. We're seeing gas prices go up 20 to 30 cents. That combined with the RFG coming in for the summer ozone season, that's causing our prices to go up a little bit," Conway said.

In the past week, local gas prices have shot up 20 to 30 cents a gallon.

Conway said there are a variety of factors, including that Marathon is the only wholesale supplier in the market.

Conway is asking the Federal Trade Commission to review the merger between Marathon and Ashland.

"Over the course of the year, we're probably between 12 and 25 cents out of whack, because we have a single wholesale supplier. And that's what's going on in Kentucky," Conway said.

According to AAA, the average price for regular unleaded gas (as of Wednesday morning) in Louisville is $3.76 while for the entire state it’s $3.52. In Indiana, the average is $3.80.

Louisville has the highest average cost for fuel in the state. Covington is $3.73, Hungtington-Ashland is $3.68, Lexington is $3.47 and Owensboro is $3.39.

In terms of larger cities in the region, Cincinnati is $3.74, Indianapolis is $3.84, St. Louis is $3.57 and Nashville is $3.27.

According to AAA, Great Lakes states (Indiana, Ohio, Illinois, Wisconsin and Michigan) are paying the second most for gas in terms of region. Those states are paying on average $3.76 per gallon while states on the Pacific West Coast are paying $3.82.

"It's not the fault of the retailer. We get calls all the time with people saying, 'Across the street they're charging this. On the other side of the street they're charging that. Is that gouging?' No, that's based on the wholesale supply they just took in," Conway said.
